VOC emissions from asphalt pavements at service temperature contribute significantly to SOA formation in urban areas.
The uptake of glyoxal (Gly) on 28 different samples with varying mineralogical origins, such as clays, mineral proxies, and natural dusts from the major arid regions Earth, was determined. Experiments were performed at ambient temperature inside a Knudsen flow reactor coupled to molecular-beam-sampling mass spectrometer. objective using high number surfaces (screening approach) identify composition–activity relationships (CAR) that link elemental composition Gly evaluate impact particle size...
Atmospheric aerosols are drivers of climate. Their impact is direct by scattering or absorbing solar radiation, and indirect, serving as cloud condensation ice nuclei. Once released into the atmosphere, can interact and/or react with gas-phase species thereby initiating a process known chemical aging. This tends to modify their surfaces. Mineral dust constitutes significant part global atmospheric aerosol mass budget, contributing almost half yearly particle emissions. Dust particles...
Outdoor air pollution is the fourth cause of death worldwide, linked to around 4.2 million deaths per year. Air more severe in urban environments cities/megacities, due high population density and intense anthropogenic activities. More than 50% global lives currently areas,1 a projected 70% anticipated by 2050,2 even reaching 84% EU.3Around 40% areas are covered asphalt pavements, fraction that keeps increasing with urbanization.4,5 Asphalt petroleum byproduct composed large number organic...
